Financial Incentives Differentially Regulate Neural Processing of Positive and Negative Emotions during Value-Based...

Area of Science:

• Neuroscience
• Cognitive Psychology
• Behavioral Economics

Background:

• Emotional and economic incentives often conflict, necessitating neural regulation of automatic emotional reactions for economically desirable decisions.
• Understanding how different financial incentive structures influence emotional regulation is crucial for decision-making research.

Purpose of the Study:

• To investigate how fixed wage (FW) and performance-based (PB) financial incentives differentially regulate neural responses to positive and negative emotional stimuli.
• To examine the neural mechanisms underlying emotion regulation in the context of conflicting economic and emotional factors.

Main Methods:

• Functional magnetic resonance imaging (fMRI) was employed to measure brain activity.
• Participants' neural responses to hypothetical colleagues, presented under FW and PB incentive conditions, were analyzed.

Main Results:

• Neural activity decreased for positive emotional stimuli and increased for negative stimuli in the middle temporal, insula, and medial prefrontal regions when shifting from FW to PB incentives.
• Performance-based incentives heightened responses in frontal and anterior cingulate regions for negative versus positive emotional decisions.
• Increased neural response to positive over negative emotional features correlated with fewer economically desirable choices.

Conclusions:

• Positive emotion regulation involves reduced activity in valence representation regions.
• Negative emotion regulation additionally recruits brain regions associated with deliberative processing and signaling of incongruous events.
• Financial incentives, especially performance-based ones, play a significant role in modulating emotional responses and subsequent economic decision-making.
